MACE-NE FOR SETTING RUBBER TIRES.

SPECIFICATION forming part of Letters Patent No. 678,653, dated July 16, 1901. Application filed February 1,1901. Serial No. 45,559. (No model.)

T at whom it nuty concern:

r the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Machines for Setting Rubber Tires, of which the following is a specification.

Our invention relates to machines for setting cushion-tires having a metallic core on the rims of vehicle-wheels; and the object thereof is to provide a machine adjustable to operate on wheels of different sizes and means by which the cores can be tightened to any desired tension and by which they can be held in suitable position to allow the workman to readily operate thereon while fitting and brazing the same and also to keep the rubber portion of said tires out of the way while the said operations are being carried on.

Our invention is illustrated in the drawings, in which- Figure 1 represents a front view of our machine. Fig. 2 is a side view of the same. Fig. 3 is a horizontal section of Fig. 1 on the line 3 3. Fig. 4 is avertical section of Fig. 1 on the line A4. Fig. 5 is averticalsection of Fig. 1 on the line 5 5. Fig. 6 is an enlarged perspective view of one portion of the table or cross-piece, showing one of the wire-straining clamps and the auxiliary clamps or Vises, together with a portion of a vehicle-rim and tire in position for setting. Fig; 7 is a sectional view of one of one of the strainingclamps through the wire-holding slot, and Fig. 8 shows an alternative form of construction of one of the auxiliary clamps or Vises.

A complete description of the machine follows, reference being had to the drawings, in which like characters of reference denote like parts throughout.

ments is balanced by a counterweight O,which is attached thereto by a chain or rope 0, passing over a pulley c, which rests on a table or flattened portion of the upright A. A shaft D, having left and right handed screw-threads cut thereon, is journaled to brackets at the extremities of the cross-piece B, and rotary motion is given thereto by the wheel (1 and the handle cl. Clamps E, having a contracted upper portion, are fitted into slots 17 in the table B and secured thereto by flattened heads b or other means, so as to have free horizontal movement. The said clamps have internally-cut screw-threads corresponding to the threads on the shaft D, which passes through and engages them. A slot e is cut in the lower portion of the said clamp, and a cam-lever c is fitted therein and secured by the pivot c.

A pair of auxiliary clamps or Vises F are mounted on the arms f, which pass through openings in the table B, to which they are pivotally attached at f The said arms are offset immediately above the clamping-blocks of the vise to pass around the shaft D, so as to bring the central line of the vise-jaws into a vertical line with the axis of the said shaft. The arms f are of curved form and are continued upwardly to pass through a slotted guide G, which is secured to the upright A in such a manner that vertical movement of the table will cause the auxiliary clamps to be moved to different distances from each other corresponding to the vertical position in which the table is placed, being brought near together as the same is lowered and having the distance between them increased as the table is raised. Provision for closing the jaws of the vise is made by the bolts f, which pass therethrough. A pin or wheel-support H is secured to the lower portion of the up right A in such a position that it is in a vertical line carried between the auxiliary j'aws F.

In Fig. 8 is shown a form of auxiliary vise somewhat different from that illustrated in other portions of the drawings. The supporting-arms are carried directly downward and the vise-jaws are included between them. By thus keeping the arms at a distance from each other immediately below the screw-shaft additional space is provided, by which the wire cores may be more readily manipulated when being placed in position to be operated upon.

The operation of our machine is illustrated in the detail drawing, Fig. 6, in which a portion of a wheel-rim with the tire in partial section applied thereto is shown. When it is desired to set a tire of the character indicatednamely, a cushion-tire having a metallic core or cores passing therethrough-the same is placed in position upon the rim of the wheel, being seated in the channel-iron I on the face thereof, and the wheel is placed upon the pin H, so as to be supported thereby, the table B being raised to permit its being placed in position and then lowered until the auxiliary clamps F rest at the bottom of the channel-iron. The angle at which the said auxiliary clamps are mounted on the armsfis such that the edges thereof are tangent to the rim of the wheel, and the curve given to the arms fis so calculated that this tangency is maintained with reference to any wheel which may be placed upon the support when the table is moved, so that the said auxiliary jaws rest upon the wheel-rim. The ends of the rubber cushion are brought into contact with the outer sides of the auxiliary clamps and the wire cores carried therethrough, so as to cross midway between them. The ends are then continued and carried through the clamps E, to which they are secured by the action of the cam-levers e. The shaft D is then turned in the proper direction to cause the clamps E to be separated from each other and carried toward the ends of the table, which operation strains the cores in opposite directions, and this operation is continued until the proper tension upon the cores is obtained. Up to this point the auxiliary jaws perform no function except that of retaining the rubber portions of the tire in a separated position as to each other. When the cores are sufficiently strained, the auxiliary clamps or Vises are closed by means of the bolts f, so as to securely grip the cores. WVhen this is done, the cores may be cut oif at the midway point and prepared for securing together, which is usually done by chamfering the ends to give a long contact and then brazing them together in that position. As soon as the wires are cut to the proper length the ends of the cores secured in the clamps E may be released and removed, the auxiliary clamps holding the cores in their strained position while the subsequent operations are carried on. The olfset form of the guide A and its projecting position from the supporting post A provides space within which a workman may readily and conveniently carry on the operations of cutting and fitting the wires and brazing them together.

We have described our invention with ref erence to a practical and operative example. The principles thereof are not limited to the constructional form shown; but

assess We claim, and desire to secure by Letters Patent, the following:
